Twilio, a company best known for supplying a communications APIs for developers has a product called Twilio Flex for building sophisticated customer service applications on top of Twilio’s APIs. Today, it announced it was acquiring Ytica (pronounced Why-tica) to provide an operational and analytical layer on top of the customer service solution.

The companies would not discuss the purchase price, but Twilio indicated it does not expect the acquisition to have a material impact on its “results, operations or financial condition.” In other words, it probably didn’t cost a lot.

Ytica, which is based in Prague, has actually been a partner with Twilio for some time, so coming together in this fashion really made a lot of sense, especially as Twilio has been developing Flex.

Twilio Flex is an app platform for contact centers, which offers a full stack of applications and allows users to deliver customer support over multiple channels, Al Cook, general manager of Twilio Flex explained. “Flex deploys like SaaS, but because it’s built on top of APIs, you can reach in and change how Flex works,” he said. That is very appealing, especially for larger operations looking for a flexible, cloud-based solution without the baggage of on-prem legacy products.

What the product was lacking, however, was a way to manage customer service representatives from within the application, and understand through analytics and dashboards, how well or poorly the team was doing. Having that ability to measure the effectiveness of the team becomes even more critical the larger they become, and Cook indicated some Flex users are managing enormous groups with 10,000-20,000 employees.

Ytica provides a way to measure the performance of customer service staff, allowing management to monitor and intervene and coach when necessary. “It made so much sense to join together as one team. They have huge experience in the contact center, and a similar philosophy to build something customizable and programmable in the cloud,” Cook said.

While Ytica works with other vendors beyond Twilio, CEO Simon Vostrý says that they will continue to support those customers, even as they join the Twilio family. “We can run Flex and can continue to run this separately. We have customers running on other SaaS platforms, and we will continue to support them,” he said.

The company will remain in Prague and become a Twilio satellite office. All 14 employees are expected to join the Twilio team and Cook says plans are already in the works to expand the Prague team.
